It publishes a journal, special publications and newsletter, organises meetings and makes various awards and grants.

The society is organised into six specialist groups, namely Foraminifera, Microvertebrates, Calcareous Nannofossils, Ostracods, Palynology and Silicofossils.

For example, the TMS joint Foraminifera and Nannofossil Spring Meeting have taken place in Denmark, France, Germany, Poland, Switzerland, and The Netherlands.

The principal aims of the BMG were to host scientific meetings and to organise multidisciplinary micropalaeontological research on British type sections from all systems, and publish the results.

The latter were the conodont, foraminifera, ostracods, pollen, spores, and non-calcareous microplankton (i.e. palynology), and other special micropalaeontological interests.

Micropalaeontology Special Publications currently include: The main committee comprises a President, Secretary and Treasurer, who each have a three-year term of office.

At each main committee meeting a representative of each specialist group (currently Calcareous Nannofossil, Foraminifera, Microvertebrate, Ostracod, Palynology and Silicofossil) should be present.
